Is it possible to use wireshark over a switched network! I'm trying to capture data packets being sent to and from a computer other than mine! I tried setting the capture filter like so 'host 10.x.x.x' (where x is a number) but after using the internet on said machine no packets are captured??? asked 11 May '12, 10:09  scorpio |
One Answer:
On a switch you will only see packets to and from your machine (and broadcasts). That's the way a switch works. To sniff in a switched environment, you need to configure a "mirror/span/monitor" port on the switch. However, this is only possible with managed switches. Another option would be the use of a simple TAP, like Dualcomm DCGS-2005 or any other cheap switch with port mirroring capabilities (e.g. HP Procurce 1810g-8). See also these links in the wiki
Also search this site for "switched network" for numerous solutions for this "problem". Regards answered 11 May '12, 10:25  Kurt Knochner ♦ edited 11 May '12, 10:26 |
